SEED-DRILL.

SPECIFICATION forming part of Letters Patent N 0. 627,964, dated July 4, 1899.

Application filed November 9,1898. Serial No. 695,919. (No model.)

To all whmm-it may concern: Be it known that I, FRANK BATEMAN, acitizen of the United States, residing at Grenloch, in the county of Camden and State of New Jersey, have invented a new and useful lmprovement in Seed-Drills for Row and Hill Dropping, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to seed-drills adapted for row and hilldropping; and it consists of improvements therein in various details, whereby a very' efficient and serviceable drill is pro duced at a minimum cost.

To the above ends my invention consists of an improved construction of marker having a rod adapted to project laterally or horizontally on either side of the machine, said rods being provided with pins thereon, which are adapted to engage a sleeve of novel construction, said sleeve being provided with recesses and having a marker attached thereto, provision being also made for enabling said sleeve to be supported in an upright or inclined position when it is desired to temporarily discontinue the use of the marker.

My invention also consists in an improved means for effecting the regulation of the discharge, this adjustment being accomplished 0 by the use of a cut-off, consisting of an apertured band located in the present instance between the opening at the bottom of the hopper and an apertured slide or gate, which is adapted to be automatically operated during the progression of the drill by means of suitable tripping devices, provision being also made for throwing said tripping device temporarily out of operation when desired, thus enabling the drill to be used for row or hill dropping, as may be desired.

It also consists of the combination of an adjustable opening-plow and a yieldingcovering-plow for covering the furrows, the latter being readily removed, if desired;

It also consists of an improved construction of ratchet mechanism and sliding-bolt mechanism common to the main wheel and to a ratchet-wheel mounted loosely on the axle of said main wheel, whereby provision is made for backing the drill without causing any rotaalso without causing any reciprocation of the slide which permits the flow of seed from th hopper to the ground.

It further consists of the combination of an adjustable cut-off and its adjuncts, whereby the flow of seed can be instantly stopped by the operator, this cut-01f preventing all loss of seed at the ends of rows, and by reason of its novel construction the same cannot be jammed by the falling of seed.

It further consists of novel details of construction, all as will be hereinafter fully set forth, and particularly pointed out in the claims.

Figure 1 represents a side elevation of a seed-drill embodying my'invention, showing the parts in assembled position. Fig. 2 represents arear elevation of Fig. 1, showing the marker and its adjuncts. Fig. 3 represents, on an enlarged scale, a section on liney y, Fig.

Figs. 4 and 5 represent sections similar to Fig. 3, showing also a portion of the hopper and its adjuncts and illustrating the different positions the cut-off may assume. Figs. 6, 7, and 8 represent transverse sections on line 0700, Fig. 3, showing the adjustable cut-off in the different positions it may assume. Fig. 9 represents a side elevation of a portion of the tripping device, certain portions of the mechanism being shown in section, the latter being taken on line 2 2, Fig. 10. Fig. 10 represents a vertical sectional view, partly in elevation, showing a sprocket-wheel, by means of which power is transmitted from 85. the main wheel to the brush or agitator and thence to the ratchet-wheel, and also a pawl or dog by means of which the slide controlling the flow of seed from the hopper is operated.

Similar letters of reference indicate corresponding parts in the drawings.

Referring to the drawings, 1 designates a seed-drill, the same consistingof the lower framework or side bars 2, to which the handles 3 are attached, the rear portion of said bars 2 being secured to the rear arms or framework 2 in which the covering-roller 3 has its bearings, said arms and covering-roller being secured in position, so that the latter can be readily removed, if desired, or when it is deemed expedient to dispense with its use. The forward portion of the bars or framework 2 has a main wheel 4 journaled therein, the latter having a sleeve 6, having flanges 5 projecting therefrom, said sleeve rotating upon the axis 6 7 designates a bolt which is mounted in the flanges 5, and has one end of a spring 8 attached thereto, the other end of said spring abutting against one of said flanges, as will be evident from Fig. 13.

One end of the bolt 7 projects exteriorly from the flanges 5, and is adapted to engage with the ratchet-teeth 9, which latter are cast or mountedupon the sprocket-wheel 10,which is mounted on the axle 6 while around said wheel passesthe chain 11, the latter engaging the sprocket-wheel 12, which is mounted upon the shaft 13,which latter also carries the brush or agitator 14, the latter being located in the lower portion of the hopper 15.

16 designates a port in the lower portion of the hopper, adjacent to which is the cut-off 17, which has a port 18 therein.

The cut-off 17 in the preferred embodiment of my invention consists of a resilient band of metalor other material, to one end of which is attached an end of the spring 19, the other end of said spring being secured to a suitable fixed point 20.

21 designates a cord or other connection which has one end secured to the cut-off 17, the other end thereof being connected to the bar 22, which latter is provided with a lug or stop 23, which is adapted to be engaged by the lever 25, which is fulerumed at the point 26.

27 designates a spring having one end attached to the lever 25, while to its other end is secured a suitable cord or connection 28, the

upper end of the latter being attached to afinger-piece or trigger 29, situated near the end of the handle 3, whereby-the lever 25, and consequently the bar 22 and the cut-off 17,

can be readily manipulated by the operator lower portion 36 of the lever 34 is bifurcated or has an opening therein, through which passes the rod 37, the opposite end of the latter being screwed or otherwise secured to the lower portion of the hopper 15.

38 designates a slide which is suitably supported below the cut-off 17 and passes freely through a guide 38 said slide having the upwardly-turned portion or abutment 39, in

which is the opening 39 and through which said rod 37 passes.

40 designates a spring interposed between the abutment 39 and the hopper, whereby the slide 38 is normally retained. in the position seen at the left of Fig. 10.

41 designates a port or opening through the slide 38, said port being preferably of rectangular shape, as indicated in Figs. 6 to 8, in which latter the position of the reciprocating slide and the adjustable cut-off are shown relatively to each other.

42 designates a tooth or lug on the exterior portion of the lever 34, said tooth beingad'apted to contact with and be operated by the cam-wheel 43, which is supported on the shaft 31, the general construction of said wheel being apparent from Fig. 10 and from the developed plan view of the latter, as seen in Fig. 16. The cam-wheel 43 is soconstrueted that one side thereof is provided with a certain number of teeth 44, as seen in Fig. 16, while the opposite side is provided with onehalf the number of teeth 45,.as will be apparent from the same figure. Each of the teeth 44 consists of the rectilinear top portion 46, the wall 47 at an angle thereto,,and an inclined wall 48, the latter being continued to the next upright wall 47. On the opposite side of the cam-wheel 43 are located the teeth ICO rod 55 and are adapted to engage recesses in the sleeve 61, the latter having located within its walls. the sockets 62, which incline in either direction, as indicated in Figs. 19 and 20, said sleeve 61 having the rod 63 attached thereto and said rod carrying the marking device 64, it being noted that said sleeve consists of the members 65, having the space 66 therebetween, whereby when the parts are in the position seen in Fig. 18 the sleeve 61 can be prevented from laterally shifting with respect to a single pin 59, or, if desired, the sleeve 61 can be placed in the space between a pair of pins 59, as shown in full lines in Fig. 2, thus permitting great freedom of adjustment of the marker, it being also apparent that the marker can be used on either side of the seed-drill, the same being readily shifted, so as to be located at the right of Fig. 2 instead of the left thereof.

66 designates a suitable frame or casting which is secured to the lower portion of the hopper and is provided with a chute or passage-way 67 for the discharge of the seed into the row or hill, said frame or casting66 having a rod 67 secured therein by means of a set-screw or other device, said rod carrying the opening-plow 68, the general construction of which will be apparent from Fig. 1, said plow being capable of vertical adjustment.

according to requirements, as is evident.

- 69 designates covering-plows, the same consisting of a pair of blades 69*, which are joined at their upper portion by a cross-piece 70, the latter having the end of a spring '71 bearing thereon, said spring passing around the stud or bolt 72 and having its other end 73 contacting with a suitable fixed point, whereby said covering-plows are normally held in a yielding position, as seen inFig. 3, and if any stone or other obstruction is encountered said plows will be permitted to yield or raise slightly, as is evident.

The operation is as follows: The forward rotation of the main wheel 4, .which is caused by the progression of the seed-drill, will rotate the shaft 13 and the brush 14, carried thereby, through the intermediacy of the sprocket-wheel 10, a sprocket-chain 11, and sprocket-Wheel 12. The motion of the shaft 13 will cause rotation to be imparted to the cam-wheel 43, and the contact of the roughened or corrugated portions thereof with the tooth 42 of the lever 34 will cause the slide 38 to be reciprocated, as will be apparent from Figs. 10 and 11, the movement to the right in the direction of the arrow (seen in Fig. 10) being caused by the raised portions of said cam-wheel 43, while the reverse movement of the left is caused through the medium of the tension-spring 40, especial attention being called to the construction of said cam-wheel, whereby one side thereof has double the number of teeth as the other side, so that the rapidity of the movements of the slide 38 relatively to the rotation of the main wheel can be increased or diminished by simply reversing the position of said cam-wheel. When it is desired toemploy the drill for rowdrilling, the latch 35 (best seen in Figs. 1

and 11) is turned into the position seen in said Fig. 11, whereby the teeth of the ratchetwheel 43 clear the tooth 42, and the lever 34 is retained forthe time being in the position indicated in Fig. 11, the shaft 13, the agitator, and brush 14 in the meanwhile revolving in unison with the rotation of the main wheel, as is evident. By reason of the bolt-andratchet mechanism common to the forward or main wheel and the sprocket-wheel adjacent thereto it will be seen thatif the drill is moved backwardly the sprocket-wheel 10 will not rotate, such rotation taking'place only during the forward movement of the drill. The adjustable cut-off 17 is readily actuated by means of the connection 28 and its adjuncts, and it will be seen from Figs. 6 to 8, inclusive, that the opening for the discharge of the seed can be regulated with great eX- actness.

The construction of the marker will be apparent from Figs. 2 and 15 to 21, inclusive, it being apparent that the rod 55 can be turned so as to extend to the right or the left of the drill, and the sleeve 61, carrying the marker, can be placed between a pair of pi'ns'59, as illustrated in full lines in Fig. 2, or, by reason of the space 66, the sleeve'can be placed in the position indicated in Fig 18,'whe rby halfspaces can be obtained, and when-it is desired to propel the drill without using the marker the latter can be turned into an up- .right position, the pin 59 engaging one of the wedge-shaped recesses 62in thesleeve 61 in the manner indicated in 20, whereby it will be seen that the marker is temporarily inoperative.

When it is desired to retain the cut-off 17 in the position seen in Figs. 5 and 8 for a considerable length of time, the trigger 29 is rotated on a pin or axis 29 in the direction indicated by the arrow a in Fig. 1 until it occupies the position seen in dotted lines in said Fig. 1, it being noted that a portion of the trigger 29 abuts against a shoulder 30 which prevents said trigger from moving in a direction opposite to that indicated by the arrow a. The trigger 29 is loosely mounted on its axis 29 in order that it may have a slight lateral play, so that when the trigger is moved in the direction indicated by the arrow I) in Fig. 2 it will abut against the shoulder 30 and will be retained by the latter in the position seen in dotted lines in Fig. 1. The shoulder 30 projects from and is a portion of a plate 31 secured to one of the handles 3, and the trigger 29 is mounted on said plate and normally rests on the stop 31, as is evident.

It will be evident that changes maybe made by those skilled in the art which will come within the scope of my invention, and I do wheels, a lever suitably fulcrumed,,a cam wheel mounted on said shaft and adapted to engage said lever, to vibrate the same laterally, and a laterally-movable, slidelocated in p x mit toithe bn n f s h ppe an haying one end situated in the path of said vibratory lever.
